If the set of manifests per node to evaluate is large, it is – to be fair _was_ [PP 3.8] – indeed possible that the master's becoming too stressed out. Can you split/maintain multiple masters? Is it really your sysinfo()[loads] being more than 16 (number of CPU cores)?

Was hoping that it was a simple parameter change, not really in a situation to run a multi-master setup.
I'm not sure what you mean by "Is it really your sysinfo()[loads] being more than 16 (number of CPU cores)?"
